Mas Amedda
this imposing, blue-skinned Chagrian served as the Old Republic's Vice Chairman, serving under Chancellor Valorum and later under Chancellor Palpatine. He spent much of his free time studying the history of the galaxy, and maintained a wealth of information on the ancient Sith. He assumed the position of Vice Chancellor less than a year before the Battle of Naboo, shortly after Valorum was first accused of violating the Amended Proprieties Bill. Senator Palpatine pointed out to Queen Amidala that Mas Amedda was another skilled politician who was only working for his own advancement, and was on the payroll of the Neimoidians' Trade Federation. However, in reality, Mas Amedda was quite loyal to Valorum and the laws of the Old Republic. He frequently reminded Valorum of the protocols required by the Galactic Senate, but was unprepared when Amidala called for a vote of no-confidence in Valorum's abilities. Mas Amedda tried to quell the uprising, but the unrest within the Senate pushed the vote to ratification. After Palpatine was voted into office as Chancellor, Mas Amedda remained loyal to the honesty of the Old Republic, a trait which made him unpopular with many Senators and politicians. Over time, Amedda became one of Palpatine's closest advisors, and remained loyal to him throughout the conflict of the Clone Wars. His knowledge of the Sith was both drawn upon and expanded by Palpatine, and Mas Amedda was able to continue his research primarily because of funding that was diverted to him by Palpatine. When Palpatine assumed the role of Emperor and instituted the New Order, Mas Amedda remained by his side for a decade.
